Setup

Load needed libraries.

# load all libraries
devtools::install_github('taikisan21/PAMpal')
library(PAMpal)
# library(kableExtra) # known bug with R ver 4.3.0 so install from github
devtools::install_github('kupietz/kableExtra')
library(kableExtra)
library(ggplot2)
library(RSQLite)
library(tuneR)
# library(wesanderson)
library(here)
library(DBI)

# I don't think we need these but saving here in case
library(dplyr)
# library(tcltk)
# library(manipulate)

Set user-defined variables.

# ProjID <- 'MHI UxS Glider Project'

# combine trip, recorder, pg version (all defined in YAML) to single run string
# dbFileStr <- paste0(params$mission, '_', params$drift, '_Kogia_', params$pgver)

# assemble some file names
# pamguard database
# dbFile <- file.path(path_to_db, paste0(dbFileStr, '.sqlite3'))

# dbFile <- choose.files(default = "", caption = "Select database file", multi = FALSE)

# specify calibration file

Define needed functions

Source some external functions

source(here::here('_code/functions', 'loadMultiBinaries.R'))
source(here::here('_code/functions', 'plotContours.R'))
source(here::here('_code/functions', 'clickSummary.R'))
source(here::here('_code/functions', 'whistleSummary.R'))

# if not using Rproj/here package use:
# source(file.path(params$path_code, 'R', 'functions', 'loadMultiBinaries.R'))

Load and prep AcousticStudies

If already created, load an existing dets PAMpal AcousticStudy object for event processing. We need to load both the unfiltered dets and filtered detsFilt AcousticStudies.

# load existing dets AcousticStudy (created with 
# workflow_generate_acousticStudies.R)
# load(detFile)
if (file.exists(detsFile)){
  dets <- readRDS(detsFile)
  cat('Loaded', detsFile, '\n')
} else {
  cat('No AcousticStudy \'dets\' file available', '\n')
}
## Loaded F:/gcp_upload/2_Acoustic-Studies/CalCurCEAS_027/CalCurCEAS_2024_027_Filtered.rdata
if (file.exists(detsFiltFile)){
  detsFilt <- readRDS(detsFiltFile)
  cat('Loaded', detsFiltFile, '\n')
} else {
  cat('No AcousticStudy \'detsFilt\' file available', '\n')
}
## Loaded F:/gcp_upload/2_Acoustic-Studies/CalCurCEAS_027/CalCurCEAS_2024_027_ch1.rdata
# summarize how many events
nEvents <- length(names(PAMpal::events(dets)))
# number of events may change after filtering (all clicks may be filtered out)
nEventsFilt <- length(names(PAMpal::events(detsFilt)))

Create initial output Event Table CSV

To be used for manual scoring based on report figures.

# set up output data frame
evTable <- data.frame(drift = character(nEvents), id = character(nEvents), 
                      species = character(nEvents), numClicks = numeric(nEvents))
# populate with drift string and event names
evTable$drift <- paste0(params$mission, '_', params$drift)
evTable$id <- names(PAMpal::events(detsFilt))

# get all click data
allClks <- PAMpal::getClickData(detsFilt)
# get the number of clicks for each event
for (iEvent in c(1:nEventsFilt)){
  evTable$numClicks[iEvent] <- length(which(allClks$eventId == evTable$id[iEvent]))
}

# keep only rows/events with at least 200 clicks
evTable <- evTable[which(evTable$numClicks >199),]

# add column for keeping/removing based on median peak frequency
evTable$keep <- FALSE # set all to false, will mark keepers as TRUE in loop

# save event table as CSV
write.csv(evTable, file = file.path(params$path_dets,
                                    paste0('eventTable_', params$mission, '_',
                                           params$drift, '_', Sys.Date(),'.csv')))

2158 events (files) in drift. 196 events have at least 200 clicks. Additional events may be removed if the median peak frequency of all high SNR clicks is less than 6 kHz. The final number of events can be found at the very end of the report.

Load reference spectra, if specified

Load the reference spectra for plotting, if set with refSpecList.

# refSpecList is specified in YAML params. Can be one or multiple species
# for single species specify as char string without quotations e.g., refSpecPc
# for multiple species, specify with call to R and c()
#     e.g., !r c('meanSpecGm', 'refSpecPc_LLHARP')

refSpecs <- NULL
if (!is.null(refSpecList)){
  refSpecs = list()
  for (rs in refSpecList){
    refSpecs[[rs]] = read.csv(file.path(path_to_refSpec, paste0(rs, '.csv')))
  }
}

Event summaries

Loop through each detection event (n = 196) create plots and a table of summary statistics for click and whistle detections. This process uses AcousticStudy objects that have detection data for each event, and also pulls information from the Pamguard binaries associated with each AcousticStudy.

Click plots (other than the SNR plot) only show clicks with SNRs >= 15 dB.
